diffusion capacitance การใช้

• The capacitance arises from various sources, mainly transistors ( primarily gate capacitance and diffusion capacitance ) and wires ( coupling capacitance ).
• In the absence of parasitic capacitances ( drain diffusion capacitance and wire capacitance ), the result is " a fan out of e " ( now N ~ ln ( C load / C in ).
• Where C _ J = \ begin { matrix } \ frac { dQ _ J } { dV _ Q } \ end { matrix } is the junction capacitance and the first term is called the diffusion capacitance, because it is related to the current diffusing through the junction.
